I've just received my first two HL lighthouses (one LE & one GLOW)plus one 4th order fresnel lens. My question to all you veteran HL collectors is should I complete the registration cards that are enclosed with each product? I notice on the classified posts that the items are usually listed as "complete with paperwork". In the event that I should sell someday is it best to have the registration form with the item or should I complete the form myself and send it in? Any advice will be appreciated.
